Calculate the entropy of a vector of probabilities, in bits. Probabilities should sum to one. Probabilities equalling zero will be ignored.
Entropy(...)
Numerics or numeric vector specifying probabilities of outcomes.
Entropy() returns the entropy of the specified probabilities, in bits.
Entropy()
# NOT RUN { Entropy(1/2, 0, 1/2) # = 1 Entropy(rep(1/4, 4)) # = 2 # }
